My agenda of reform to transform is yet to be finished: PM Modi

New Delhi, Jul 18: The Covid-19 lockdown-led reduction in air pollution levels across five Indian cities, including Delhi and Mumbai, may have prevented about 630 premature deaths, and saved USD 690 million in health costs in the country, according to a new study.

Scientists, including those from the University of Surrey in the UK, assessed the levels of harmful fine particulate matter (PM2.5) from vehicles and other sources in five Indian cities -- Delhi, Mumbai, Kolkata, Chennai and Hyderabad -- since the beginning of the lockdown period.

The study, published in the journal Sustainable Cities and Society, compared these lockdown PM2.5 figures from 25 March up until 11 May, with those from similar periods of the preceding five years, and found that the measure reduced pollution levels in all these places.

According to the scientists, during this period, the levels of these harmful air pollutants reduced by 10 per cent in Mumbai, and by up to 54 per cent in Delhi.

"The percentage reduction for the other cities ranged from 24 to 32 per cent, which was slightly smaller than the measured values for Delhi and Mumbai," the scientists noted in the study.

"While the reduction in PM2.5 pollution may not be surprising, the size of the reduction should make us all take notice of the impact we have been having on the planet," said Prashant Kumar, a co-author of the study from the University of Surrey.

The scientists said these reductions in PM2.5 were comparable to those reported in other cities across the world, such as in Austria's capital Vienna (60 per cent), and Shanghai (42 per cent) in China.

They also calculated the monetary value of the reduced mortality due to air pollution and found that the lowered levels of PM2.5 may have saved 630 people from premature death, and USD 690 million in health costs in India.

Coronavirus India update: State-wise total number of confirmed cases, deaths on July 17

According to the researchers, the present lockdown situation offers observational opportunities regarding potential control systems and regulations for improved urban air quality.

They said an integrated approach might help in understanding the overall impacts of Covid-19 lockdown-style interventions and support the implementation of relevant policy frameworks.

"This is an opportunity for us all to discuss and debate what the 'new normal' should look like - particularly when it comes to the quality of the air we breathe," Kumar said.

Thiruvananthapuram, Apr 22: Eleven more people tested positive for COVID-19 in Kerala with totalpositive cases in the State touching 437on Wednesday.

Jun 3: Emphasising that airlines are clearly the safest mode of transportation, IndiGo CEO Ronojoy Dutta on Tuesday said there is no evidence yet of coronavirus infection getting transmitted among passengers onboard an aeroplane.

His comments against the backdrop of instances of some passengers, who had taken flights after resumption of domestic air services on May 25, testing positive for coronavirus.

"Those people had the virus before they got on to the aeroplane. What is noteworthy is that they have done the tracing after that. There is no evidence of transmission onboard there... that is a very encouraging sign on the safety of airline travel," he said during an earnings call.

According to him, airlines are clearly the safest mode of transportation and there is no evidence yet of contamination on an aircraft.

"You can come in contaminated but so far there is no evidence of passing it on to a fellow passenger," he noted.

Amid concerns over the coronavirus pandemic, aviation regulator DGCA has asked airlines to ensure that to the extent possible, middle seat in flights should be kept empty.

In this regard, Dutta said the airline would keep the middle seat empty wherever it can and "where we have to fill the middle seat, we will have the extra protective gown".

To a query about possible hedging of fuel prices, he said it would be a dumb idea and that airlines adjust to ups and downs in fuel prices.

"I can't overemphasise what a dumb idea it will be for an airline to hedge fuel prices. I looked at it from different angles and it is not a good idea... we looked at hedging and we talked about it at the board level and we said no," he noted.
